Oil level too high?
 

My oil level is right on the lower line of the "H". Is this dangerously high, or will I be fine? I know over filling can be just as bad as underfilling.

Between L and H is considered normal. You are OK. FWIW, I try to keep mine at about 75% but don't get obsessive about it.

Its past the hash area so thats why i was worried

Don't worry about it. You can overfill by a lot and still not have any issues. It isn't like our crank is turning in the oil like an old chevy 350.

Drain a little bit of it out or gun it when its cold to burn some of it off if its really worrying you.

Does it break after the hash or before and there is oil after the hash? You go off where the first break in oil is.

Either way if you're not overfilled by much you should be fine, just make sure you're not a quart too much though because you might get air I'm the system.

the level is literally right where the bottom line of the "H" is. the manual recommends between the 2 holes in the dipstick, but since the level is above that point thats why i was wondering if it's a big deal? Would the level being at the bottom line of the "H" be less than a full quart overfilled?

I wouldn't worry about it. You won't do any harm but I wouldn't recommend do this on a regular basis. I have heard older cars (pre-80s) had more issues with this.

I didn't do it myself, the shop did when they were fixing up my oil cooler leak, I'm sure they didn't do it on purpose though. Most people wouldn't even care, but I'm a bit anal if you can't tell.

Assuming that the two holes equal a quart of oil (32 fl oz), you're only talking 2-4 extra fl oz of oil. (Not sure how good that assumption is, but it should be fairly close.)

If it were a lot easier to drain a little oil from the engine, I'd say do it. As it is, I wouldn't worry about it. If you're that obsessive about it, get a piece of small tubing and a siphon bulb and suck the excess out from the dip tube.

So you're saying if there is nothing on the dip stick your only a quart low? I would think imagine it would take more than a quart low to show nothing on the dipstick...

wat, there was hash mark and H?

I keep mine around the top dot to about 3mm down.

Assuming the distance between the two holes is 1 qt and that distance on the stick vs. oil volume is linear, the bottom of the stick looks to me like it would be about 3/4 of a quart too low.

Just go ahead and suck some oil out through the dip tube and be done with it.

No there isn't any hash mark, just a L, 2 dots, and an H.

Kinda like this: L o----------o H

My level is basically right on the first line of the "H".

anyone know around how many quarts above this would be?

You're overthinking this. Remove about a half-pint of oil into a clean container. Check the stick. If you took too much out, pour some back in (aren't you glad you used a clean container?). Repeat until level is 25-75% (edit: or whatever you fell comfortable with) between the dots. Just about every hardware store sells siphon bulb pumps (think squeeze bulb on blood pressure cuffs) for ~$5. You may need to get some smaller outside diameter (OD) tubing to fit down the dip tube.

Well i figured if im half a quart or less ill be able to sleep at night w/o going through the trouble. Thats why i'm wondering about how much over i am.

Let's assume that the distance between the holes is two quarts (64 fl oz). The "H" is a tenth to an eight (10-12.5%) of that distance above the top hole (using my eyeball micrometer). So that would be ~16 fl oz (1/2 quart). I pretty sure it's closer to one quart between the holes.

It's a handy piece of info for the guys at the dealerships that do oil changes, so how much oil between-the-dots represents may be in the Owner's Manual and/or the FSM.

This thread is hilarious.

If that's the case then I'm sure the amount I'm over is not enough to think twice about (even though I already have!). I'm sure the engineers have designed the engine to allow for a small amount of accidental overfill. I mean just think of all the people out there with this car, I'm sure there is plenty who have had the level a tad over without having a negative impact on their engine.

oh, thanks for the clarification.... im starting to lose my sight. :ugh:

my G35C's dip stick has hash markings (no dots), so this is why i wondered. :D

oil level
 

To get to the just of this reply; plesae check back to my original post "oil change" back in 7/21/13. From observation and experimentation, i have found that a bad oil stick reading can be in a matter of inches or feet. I use to check my oil hours or days after an oil change. the oil dip stick would read at the H mark. Since nissan was doing the the oil change; i thought this is where the dip stick was suppose to read. I would read the dip stick on level ground in my garage( the car did not roll forward or backwards) So after assuming Nissan's were the bad guys; i took out my level and check my garage floor were the car was placed to check the oil. IT WAS LEVEL. I checked another spot in my driveway. IT WAS LEVEL. But get this; two different dip stick readings. In my garage was high, in the driveway just were it was suppose to be. In conclusion; checking your oil on unfamiliar ground could get you a bad reading of the dip stick. But finding a sweet spot where you can check your oil everytime will give you the best reading.
